Here is my MWE, which shows that citations appear in a (seemingly) inconsistent way:
\documentclass{report}
\usepackage[UKenglish]{babel}
\usepackage[latin1]{inputenc}
\usepackage{csquotes} % Seems to be needed by biblatex
\usepackage[backend=biber,sorting=nyvt,style=authoryear,natbib,doi=false,eprint=false]{biblatex}
\DeclareNameAlias{sortname}{family-given}% This ensures the correct ordering of the first name and the last name in the bibliography
\bibliography{Biblio} % Overleaf uses/recommends to use \addbibresource{Biblio.bib} instead of \bibliography.
% for having a self-contained example:
\usepackage{filecontents}

Here is the result:
My questions are:
Why are the citation formats so different? I don't recognise a pattern when they appear in which format. How can I achieve that only family names (and no given names or initials) are printed in the citations with \citet and \citep?
How can I achieve (without modifying every bibtex entry) that in the Bibliography, every name is in the format
family-name, initials-of-given-namelike for exampleKirk, J. T.
I have already tried the option giveninits=false, but it has no effect. I have also tried (just for curiosity) the option maxcitenames=1. It works at some places, but it does not work at other places.
I know the answer is "it's no inconsistency, it is a feature". But then please tell me how this feature can usefully be applied.
uniquenameanduniquelistto stopbiblatexfrom adding name initials or more names thanmaxcitenames/you expect (set both options tofalse). See https://tex.stackexchange.com/q/134535/35864 and https://tex.stackexchange.com/q/69028/35864. – moewe Nov 08 '21 at 16:50giveninits=true,and notgiveninits=false,(i.e. you wantbiblatexto produce initials and not the full name), so you set the option totrue. – moewe Nov 08 '21 at 16:52@moewe: Thanks, perfectly solved!

biblatexwill not truncate names of citations if doing so would cause ambiguous citations. This was sometimes the case, when I had more references in my file and it led to some citations having five or seven names. To force biblatex to truncate and to write 2014a and 2014b instead,uniquelist=falseis ideal.Once again big thanks, @moewe
